Description

Technical Field

[0001] This utility model relates to the field of three-way valve technology, specifically a corrosion-resistant and wear-resistant composite structure for the valve body of a three-way valve. Background Technology

[0002] A three-way valve is a hydraulic control device that integrates the functions of a check valve, a safety valve, and an unloading valve. It is mainly used in mining machinery (such as external injection single hydraulic props) and is known as a "life-saving valve." However, the sealing structure of traditional three-way valves is prone to deterioration in sealing performance and leakage problems during long-term use due to factors such as media erosion and pressure fluctuations.

[0003] According to the three-way valve seal disclosed in Chinese patent CN222084531U, the existing three-way valve has a direct connection between the valve body and the valve seat via threads, and there is no locking mechanism after the connection. This makes the connection prone to loosening, which leads to the risk of leakage at the threaded connection seal. This greatly reduces the sealing efficiency of the valve body and valve seat and is suitable for widespread promotion and use.

[0004] The aforementioned devices cannot pre-treat the medium as it enters the valve body, failing to block impurities and particles in the medium. These impurities may corrode sealing components, reducing sealing performance and leading to external leakage. Therefore, we provide a corrosion-resistant and wear-resistant composite structure for the body of a three-way valve. Utility Model Content

[0005] The purpose of this utility model is to provide a corrosion-resistant and wear-resistant composite structure for the body of a three-way valve, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant and wear-resistant composite structure for a three-way valve body, comprising: a valve end;

[0007] A threaded connector is threaded to the right inner wall of the valve end.

[0008] The valve body is fixedly connected to the right side of the threaded connector;

[0009] A connecting assembly is fixedly connected between the valve end and the valve body; the connecting assembly includes a sealing part fixedly connected between the valve end and the valve body, and the sealing part is connected to a protective part.

[0010] Preferably, the sealing part includes a sealing ring fixedly connected to the outer wall of the right end of the threaded connector, a sealing sleeve being snapped onto the outer wall of the sealing ring, an adjusting block being fixedly connected to the left side of the sealing sleeve, the bottom end of the adjusting block being slidably connected to the inner surface of a groove, the groove being formed on the outer wall of the right end of the valve, a limiting groove being formed on the inner surface of the groove, a limiting rod being snapped onto the inner surface of the limiting groove, and the outer wall of the limiting rod being rotatably connected to the bottom end of the adjusting block.

[0011] Preferably, the protective part includes a filter sleeve that is snapped onto the outer wall of the left end of the valve end. A mounting ring is fixedly connected to the right side of the filter sleeve. The inner wall of the mounting ring is threaded to the outer wall of the right end of the valve end. A connecting rod is fixedly connected to the right side of the mounting ring. An extension rod is fixedly connected to the bottom of the right end of the connecting rod. A movable groove is formed on the left side of the outer wall of the extension rod. A fixing rod is fixedly connected to the inner surface of the movable groove through an elastic sheet. The end of the fixing rod away from the elastic sheet is snapped onto the inner surface of the fixing groove. The fixing groove is formed on the right side of the sealing sleeve.

[0012] Preferably, the two sides of the sealing ring are in contact with the right side of the valve end and the left side of the valve body, respectively, which can effectively fill the gap between the valve end and the valve body and prevent media leakage.

[0013] Preferably, the sealing sleeve is arc-shaped, and there are two sealing sleeves, which are symmetrically attached to the upper and lower ends of the sealing ring, respectively. The arc-shaped sealing sleeve can better fit the outer surface of the sealing ring, increase the sealing contact area, and further improve the sealing performance.

[0014] Preferably, the two ends of the limiting rod are slidably engaged with the inner surfaces of the two limiting grooves, thereby limiting the sliding range of the adjusting block and ensuring the stability of the sealing sleeve position.

[0015] Preferably, the right end of the fixing rod is movably inserted into the inner surface of the movable groove, so that the fixing rod can be easily pulled out of the fixing groove when needed, facilitating individual maintenance, inspection or replacement operations.

[0016] Compared with the prior art, this utility model provides a corrosion-resistant and wear-resistant composite structure for the body of a three-way valve, which has the following beneficial effects:

[0017] 1. The three-way valve body features a corrosion-resistant and wear-resistant composite structure. The sealing ring fits tightly against the valve end and valve body, and is securely held in place by two upper and lower arc-shaped sealing sleeves. This effectively prevents media leakage from the connection between the valve end and the valve body, providing a reliable sealing guarantee for the normal operation of the three-way valve. The adjusting block can slide within the groove, facilitating fine-tuning of the sealing sleeve position during installation to achieve the best sealing effect. This ensures that the sealing performance is maintained during long-term use, reducing the risk of sealing failure due to loose components.

[0018] 2. The three-way valve body features a corrosion-resistant and wear-resistant composite structure. Through the filter sleeve, it performs preliminary filtration of the medium entering the valve, effectively blocking impurities and particles. This significantly reduces wear and corrosion of internal valve components, extending the valve's service life. Simultaneously, the threaded connection between the mounting ring and the valve end provides a solid foundation for the filter sleeve, ensuring it won't loosen or fall off during operation. The fixing rod securely engages with the fixing groove, increasing the filter sleeve's stability and further enhancing the stability of the sealing sleeve. The elastic plate connecting the fixing rod provides a degree of elasticity during engagement, facilitating installation and disassembly. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Example 1: The corrosion-resistant and wear-resistant composite structure of the three-way valve body provided by this utility model, such as... Figures 1 to 6 As shown: A corrosion-resistant and wear-resistant composite structure for a three-way valve body, comprising: valve end 1;

[0029] Threaded connector 2 is threaded onto the right inner wall of valve end 1;

[0030] Valve body 3 is fixedly connected to the right side of threaded connector 2;

[0031] A connecting assembly 4 is fixedly connected between valve end 1 and valve body 3; the connecting assembly 4 includes a sealing part 41 fixedly connected between valve end 1 and valve body 3, and a protective part 42 is connected to the sealing part 41.

[0032] The sealing part 41 includes a sealing ring 411 fixedly connected to the outer wall of the right end of the threaded pipe 2. A sealing sleeve 412 is snapped onto the outer wall of the sealing ring 411. An adjusting block 413 is fixedly connected to the left side of the sealing sleeve 412. The bottom end of the adjusting block 413 is slidably connected to the inner surface of the groove 414. The groove 414 is opened on the outer wall of the right end of the valve end 1. A limiting groove 415 is opened on the inner surface of the groove 414. A limiting rod 416 is snapped onto the inner surface of the limiting groove 415. The outer wall of the limiting rod 416 is rotatably connected to the bottom end of the adjusting block 413.

[0033] In this embodiment, the two sides of the sealing ring 411 are in contact with the right side of the valve end 1 and the left side of the valve body 3, respectively, which can effectively fill the gap between the valve end 1 and the valve body 3 and prevent medium leakage.

[0034] Preferably, the sealing sleeve 412 is arc-shaped, and there are two sealing sleeves 412, which are symmetrically attached to the upper and lower ends of the sealing ring 411 respectively. The arc-shaped sealing sleeve 412 can better fit the outer surface of the sealing ring 411, increase the sealing contact area, and further improve the sealing performance.

[0035] Preferably, the two ends of the limiting rod 416 are slidably engaged with the inner surfaces of the two limiting grooves 415, thereby limiting the sliding range of the adjusting block 413 by the limiting rod 416, thus ensuring the stability of the position of the sealing sleeve 412.

[0036] Example 2: Based on Example 1, the three-way valve body corrosion-resistant and wear-resistant composite structure provided by this utility model, such as... Figures 1 to 6 As shown: The protective part 42 includes a filter sleeve 421 that is snapped onto the outer wall of the left end of the valve end 1. A mounting ring 422 is fixedly connected to the right side of the filter sleeve 421. The inner wall of the mounting ring 422 is threadedly connected to the outer wall of the right end of the valve end 1. A connecting rod 423 is fixedly connected to the right side of the mounting ring 422. An extension rod 424 is fixedly connected to the bottom right end of the connecting rod 423. A movable groove 425 is provided on the left side of the outer wall of the extension rod 424. A fixing rod 427 is fixedly connected to the inner surface of the movable groove 425 through an elastic piece 426. The end of the fixing rod 427 away from the elastic piece 426 is snapped onto the inner surface of the fixing groove 428. The fixing groove 428 is located on the right side of the sealing sleeve 412.

[0037] In this embodiment, the right end of the fixing rod 427 is movably inserted into the inner surface of the movable slot 425, so that the fixing rod 427 can be easily pulled out from the fixing slot 428 when needed, which facilitates maintenance, inspection or replacement operations.

[0038] In actual operation, when this device is used, the threaded connector 2 is first threaded to the right inner wall of the valve end 1, and the sealing ring 411 fits tightly against the valve end 1 and the valve body 3. It is also firmly secured by the upper and lower arc-shaped sealing sleeves 412, which can effectively prevent the medium from leaking from the connection between the valve end 1 and the valve body 3, providing a reliable sealing guarantee for the normal operation of the three-way valve. At the same time, the adjusting block 413 can slide in the groove 414, which makes it easy to fine-tune the position of the sealing sleeve 412 during installation to achieve the best sealing effect, so that the sealing performance can be maintained during long-term use and reduce the sealing failure problem caused by loose parts. By rotating the adjusting block 413 in the opposite direction, the sealing sleeve 412 can be disengaged from the sealing ring 411, making installation and disassembly convenient.

[0039] The filter sleeve 421 is snapped onto the outer wall of the left end of the valve end 1. Then, the mounting ring 422 is threaded to the outer wall of the right end of the valve end 1 through the thread on its inner wall. During the tightening of the mounting ring 422, it is necessary to ensure that the installation is firm and to provide stable support for the filter sleeve 421. Due to the presence of the elastic plate 426, appropriate force can be applied when snapping the fixing rod 427 to make the fixing rod 427 smoothly snap into the fixing groove 428. After installation, the elastic plate 426 will provide a certain amount of elasticity to ensure that the connection between the fixing rod 427 and the fixing groove 428 is tight, and at the same time, it will further stabilize the installation of the sealing sleeve 412.

[0040] The medium is then filtered through the filter sleeve 421 to remove impurities and particles before entering the valve body 3. The sealing part 41 ensures that the medium will not leak from the connection between the valve end 1 and the valve body 3. The protective part 42 and the sealing part 41 work together to effectively improve the corrosion resistance and wear resistance of the three-way valve body.
